What Does it Mean When Your Check Engine Light Comes On?

Don’t Panic!

No one likes it when their check engine light comes on. That little yellow light is designed to be a stressor, meant to prod you into action so that you’ll take your car in for maintenance as soon as possible. But what does it mean when the check engine light comes on? In this blog post, we’ll explore a few of the most common reasons why your check engine light might be illuminated.

The Causes Of A CEL

One of the most common reasons your check engine light might be illuminated is that your vehicle’s emission control system is malfunctioning. The emission control system includes a number of different parts, all of which work together to reduce the amount of harmful pollutants that your car emits. If any one of these parts isn’t working correctly, it could trigger the check engine light.

Another reason your check engine light might come on is an issue with your ignition system. The ignition system provides the spark that ignites the air/fuel mixture in your car’s cylinders. If there’s a problem with this system, it can cause your car to run less efficiently and can also trigger the check engine light.

There are a number of other potential reasons why your check engine light might come on, including problems with your oxygen sensor, fuel injectors, or catalytic converter. If you’re unsure about what might be causing your check engine light to come on, the best course of action is to take your car to a certified mechanic for diagnosis and repair.
